Answer:
254 ft
Explanation:
first find the legs of the triangle.
you already know 65, and you would get another leg by 83-50, which equals 33.
Next use pythagorean theorem to find the other leg
a^2+b^2=c^2
rearrange so you find a leg
a^2=c^2-b^2
a^2=65^2-33^2
a^2=4225-1089
a^2=3136
a=56
Now you know that the missing leg is 56. Since that leg is the same as the short side of the rectangle, you 83+50+65+56=254
